ASCO 7000 SERIES PCS offers the most advanced power management capabilities available today. Because every 7000 SERIES PCS is custom-engineered to meet site and application requirements and customer expectations. Every customer receives the full benefit of a century of ASCO critical power expertise.
CUSTOM POWER MANAGEMENT FOR EVERY FACILITY
ASCO 7000 PCS maximizes load distribution and generator efficiency based on real-time generation capacity and demand. PCS controllers apply sophisticated strategies for connecting and disconnecting power sources and loads. They also connect load banks to meet loading requirements for diesel-powered generators.

Because every ASCO 7000 SERIES PCS is custom-engineered for a specific application, facilities benefit from feature optimization at every level:
• Custom sequences for optimizing usage of power source capacity• Capabilities to manage paralleling of multiple generators, including both diesel and natural gas-fired units• Capabilities to switch between or parallel utility, generator, and renewable power sources• Custom bus configurations to hasten generator start-up and connection, increase redundancy, and maximize
availability• Custom sequences for adding, shedding, and managing loads and keeping them online
Paralleling Multiple Sources
Monitoring and synchronizing generators is essential for any electrical system served by more than one power source. ASCO 7000 SERIES PCS synchronize and connect multiple sources after comparing voltage, frequency, and phase angle. They can parallel multiple bus segments to connect priority loads quickly.
Generator Load Demand
Generator Load Demand maximizes the efficient use of standby generator capacity by adding or removing generators according to demand. It ensures reliability and availability by connecting sufficient power when needed. It conserves fuel and reduces engine-generator wear-and-tear by operating fewer generators at higher efficiencies.
Parallel Different Types of Power Sources
Bringing power from both a utility feed and a generator can offer significant operational flexibility and cost benefits. More than 50 years ago, ASCO produced its first system for paralleling utility with generators, and we have designed, manufactured, installed, and supported utility paralleling applications ever since.
GET THE MOST FROM POWER SOURCES
The benefits of paralleling different power sources include:
• Utility Load Curtailment – When utilities direct users to reduce demand, facilities can use generators to provide supplemental power instead of curtailing load.
• Peak Shaving – To avoid demand charges, facilities can run generators to replace a portion of utility power during peak use periods.
• Parallel Utility, Generators, and On-Site Renewables - Parallel two or more power sources to enhance reliability, reduce energy consumption, and lower energy costs. Support microgrids and integrate renewable power sources for a greener, more sustainable facility.

Bus Optimization
ASCO 7000 PCS are available with either of two bus optimization capabilities.
Standard Bus Optimization evaluates the available capacity of online generators and compares it to the maximum expected value of the next priority load block. If the generation capacity is sufficient, load is added to increase utilization.
Dynamic Bus Optimization can further increase generator utilization. By using power meters to measure discrete loads, a PCS systems can more precisely compare capacity and real-time demand. This approach identifies the maximum available capacity to get discrete loads online and maximize generator usage.
Priority Pass-Along
ASCO 7000 SERIES PCS systems add and shed loads in the order of their assigned priorities. If a low-priority Automatic Transfer Switch (ATS) loses its normal power source before other high-priority loads, engine-generators start and supply power to the affected ATS. If other ATSs subsequently require backup power, PCS controllers add them according to the previously assigned priorities. This ensures that impacted low-priority loads are quickly transferred to the alternate power source, without delays that could otherwise occur using other load prioritization schemes.
ADD AND KEEP MORE LOAD ONLINE
Assigning unique and structured priorities to loads enables sophisticated power management strategies. When loads are prioritized, PCS controllers can man-age transfer switches and circuit breakers to add or shed individual or block loads.
ASCO 7000 SERIES PCS products provide unsur-passed power distribution control by managing up to 128 prioritized transfer switches and/or electrically op-erated circuit breakers. Assigning sub-priorities to dis-creet loads in load blocks refines control to maximize generator utilization.

With Priority Pass-Along, the loss of normal power at ATS 3 triggers an engine start. If normal power is subsequently lost on other ATSs, they would be added to bus in prioritized order - in this case, ATSs 1 and 2 together, then ATS 4.
Load Latch
ASCO 7000 SERIES PCS features Load Latch, which first compares the total unused capacity of the remaining online generators to the real-time demand of the online load blocks. This feature prevents unnecessary disconnection of loads, another way that ASCO PCS solutions enhance critical power availability. Without Load Latch, the failure of one engine-generator could unnecessarily shed an entire priority block of loads.

Manual Load Controls
ASCO PCS provides manual controls to maximize operating flexibility, including:
Load Shed Bypass/Reset: Dedicated hardware for manually re-adding shed load blocks. To protect generators, any excess loads are automatically re-shed.
Hand-Off-Auto: Touchscreen controls for manually connecting individual automatic transfer switches and circuit breakers to the main bus.
Manual Paralleling: Allows manual connection of generators to the main bus if automatic paralleling becomes inoperable.
Load management strategies are important for optimiz-ing power systems performance. Learn more by review-ing our PCS Load Management white paper. It is avail-able at www.ascopower.com and can be downloaded by clicking here.

Advanced Bus Segmentation
ASCO 7000 SERIES PCS products offer the flexibility, reliability, and performance benefits of multiple bus configuration options.
CONFIGURE BUS TO MAXIMIZE PERFORMANCE
Single Bus is the simplest and most cost effective configuration for managing a limited quantity of power sources and loads:
• Synchronize generators as each engine reaches operating speed and voltage
• Manage connection of loads to the bus according to available generator capacity
• Shed the lowest priority loads to match available bus or generation capacity

Segmented Bus. Adding one or more tie breakers between bus segments enables power systems to:
• Concurrently connect generators on isolated segments to bring multiple gensets online within the 10-second timeframe required for critical power applications
• Distribute remaining generation capacity to the loads on each bus when segments are tied together – this increases overall capacity to maximize availability if a generator fails
• Isolate faults if one bus is lost, keeping the remainder of the facility powered

Ring Bus. If a generator or bus segment fails, ring architecture enables power to be distributed from any remaining sources to any remaining loads. This configuration enhances the ability to isolate faults to the segment on which they occur. Often used on medium voltage applications, ring configurations provide higher levels of redundancy and availability.

EFFICIENT REGULATORY REPORTING
When equipped with the ASCO Critical Power Monitoring System (CPMS), ASCO 7000 SERIES PCS generate and distribute documents that make industry and regulatory reporting easy. Generators can be monitored through ASCO Power Metering Units and accessories, or directly using Modbus protocols. CPMS systems automatically track facility and equipment performance during outages and test events, and begin recording power data when a transfer switch or an engine-generator changes state.
After the last switch has re-transferred to its Normal power source, a detailed report is automatically generated and emailed to recipients designated by the user. The CPMS stores the information on a server, which may be used to comply with industry and regulatory reporting requirements including NFPA 99, NFPA 110, Joint Commission, CALEA, and CMS. For additional information, see the CPMS Overview brochure and our white paper entitled Automated Reporting for Emergency Power Systems.
